Abstract

A novel laser oscillator with a cavity completed by the refractive-index grating induced by generating beams in a nematic liquid-crystal cell is studied experimentally and theoretically. It is shown that both the thermal and orientational nonlinearity of the liquid crystal can provide the holographic mirror formation and the self-starting condition in the laser oscillator. The self-starting laser with a nonlinear mirror demonstrates a single-longitudinal-mode generation with good beam quality.
